Embedded business metadata

ABSTRACT

A methodology is disclosed for improving searches of a distributed Internet network. A distributed Internet network is searched for a particular information type, searching for a field identified using a predetermined identifier indicating that the field comprises information of the particular information type. When the field identified using the predetermined identifier is found, an association of the contents of the field with the search results is made, and repeated using the same predetermined identifier. Information of a particular information type may then be served in a field identified using a predetermined identifier that identifies the field as containing information of the particular information type.

PRIORITY CLAIM

This application is a continuation of co-pending application Ser. No.12/287,095, entitled “EMBEDDED BUSINESS METADATA,” filed Oct. 6, 2008,the disclosure of which is incorporated in its entirety herein.

FIELD OF THE INVENTION

The present invention relates generally to electronic businessadvertising services and e-commerce, and more particularly, to methodsfor improving searches of a distributed Internet network, such as theWorld Wide Web, and other services accessible over the Internet.

BACKGROUND OF THE INVENTION

Finding relevant, accurate business information on the Web in anefficient manner can still be a challenge. While a variety of national,regional and local Web sites and portals provide basic information forconsumers, those sites have many shortcomings. For example, a consumercan find basic information about restaurants such as restaurant type,street address, phone number and hours of operation with just a fewkey-strokes or mouse clicks. Additional information, which can becritical to selecting a restaurant, is more difficult or just impossibleto determine without an extensive search of the establishment's Website. For example, a consumer may wish to know about payment options,availability of a kids menu, approximate price range, dress code or thedaily specials. A phone call to the restaurant may be necessary toclearly answer all the questions. That becomes impractical when evenonly a few possible restaurants are identified by a quick search.

Search engines such as Google™ and Yahoo!® search for information on theWeb. The information may be Web pages, images and other types of files.The search function generally includes three steps: visiting and cachingWeb pages, Web indexing and presenting search results to the user.

Search engines may employ a Web crawler, an automated program thatbrowses the Web to constantly search or crawl and return the most recentrevision of pages encountered to be copied or cached. The dynamic natureof the Web is that pages are constantly being added, changed or deleted.Once pages are cached, they can be processed with an algorithm oralgorithms to rank or index them. That process is referred to as Webindexing, with the purpose of optimizing speed and performance when aspecific search request is made. Web pages are typically crawled withsome frequency such as daily, weekly or monthly, which can lead tooutdated or incorrect information being returned by a search.

Web pages are designed to be viewed or read by people. However, duringthe process of indexing the Web pages, words, context and intendedmeaning may be inadvertently changed or lost as a result of the indexingprocess itself. Natural language processing is the study of the problemsof automated generation and understanding of natural human language.Indexing algorithms must accurately capture the intended meaning ofpages they encounter or the indexing will be inaccurate, ultimatelyleading to inaccurate search results presented back to the user.

Metadata is defined as “data about data,” of any sort, in any media.Metadata may describe an individual data item in a database (DB) such asan individual customer name or account number, or a collection of datasuch as an entire customer record as determined by its context and howit may be used. Metadata can be used to speed up and improve a qualityof a search by saving the users from performing more complex queryfilter operations manually.

The use of metadata can improve Web indexing by providing context orotherwise improving the understanding of the data. Metadata, however, isfrequently used by Web page designers to provide unseen key words orphrases to search algorithms. That data is not really “data about data”at all. Many search engines now have algorithms to screen out suchextraneous metadata. The screening algorithms are not infallible, sothere can be instances where inappropriate results may be presented thathave escaped the best efforts of the Web indexing algorithms.

A tag is metadata in the form of a user-selected word or term associatedwith or assigned to a piece of information. The tag describes thatinformation. This is in contrast to hierarchical systems that usetraditional “tree” structures where folder and sub-folder arrangementsare used. Tagging allows users to quickly and easily attach multipletags, and change or delete tags. Both data and metadata can be tagged.For example, computer files, audio files, video files or playlists, Websites, Web pages, Internet bookmarks of favorite Web sites and manyother data types may be tagged. A Web page hosted on a Web server orblog server that supports tagging, might have the tags “Baseball,”“Yankees,” “Tickets,” “Away Games,” and “Discounts.” A human reader maybe able to tell the purpose of the page by quickly scanning the list oftags, in this case discounted Yankees baseball tickets for an away game.

Specially designed server software may be used for tracking, updatingand facilitating searching with tags, and utilizing suitable algorithmsto improve the efficiency and effectiveness of multiple-tag searches. Inthis example, the server software may display the tags in a list on apage, with each tag displayed as a Web link leading to an index pagelisting all Web pages that use that tag. This could allow a reader toquickly locate pages that have been associated with a tag or group oftags. If the author of the Web page would like to change the way thepage is found through a search, the list of tags can be changed.

While using tags in such an organizational system is flexible and easy,tagging is not without its drawbacks. Typically there is no informationabout the meaning or semantics of a tag. For example, the tag “Lab”could refer to a Labrador retriever, a national lab such as Los AlamosNational Lab or any company or person with “lab” in their name. Thislack of semantic distinction in tags can lead to inappropriateconnections between items yielding inappropriate search results.Additionally, selection of tag terms is largely non-standardized and maybe user specific. Users may use drastically different terms to describethe same concept. Users of tagging systems must make judgments, based onthe number of connections and the choices of tag terms and whetherpossible connections between items are valid for their particular use orinterests.

Tag classification and the concept of connecting sets of tags betweenWeb/blog servers, has led to the rise of “folksonomy” classification,the concept of social bookmarking, and other forms of online communitiesand social networking software. Folksonomy is defined as the method ofcollaboratively creating and managing tags to annotate and categorizelinks and/or content. Larger-scale folksonomies tend to address some ofthe problems of tagging, as astute users of tagging systems willmonitor/search the current use of tag terms within these systems, andtend to use existing tags in order to easily form connections to relateditems. In this way, evolving folksonomies define a set of taggingconventions through eventual group consensus.

Although tagging is often promoted as an alternative to organization bya hierarchy of categories, more and more online resources use a hybridor mixed system, where items are organized into broad categories, withfiner classification distinctions being made by the use of tags.

vCard is a file format for electronic business cards. vCards areexchanged electronically, and are often attached to email messages orcopied from the Web. The format has provisions for name and addressinformation, phone numbers, URLs, logos, photographs, audio clips andmore.

It would therefore be desirable to provide a technique for searchingdistributed Internet networks for a particular information type, whileminimizing or eliminating unwanted or incorrect search results. There isfurthermore a need for more focused searching techniques that yieldresults that are difficult to obtain using a natural language ortraditional tag search. To the inventors' knowledge, no such system ormethod currently exists.

SUMMARY OF THE INVENTION

In accordance with a first aspect of the present invention, there isdisclosed a method for searching for data in a distributed Internetnetwork. The method generally comprises the steps of: receiving asearching target, the searching target comprising a particularinformation type; searching a first served information grouping for afield identified using a predetermined identifier indicating that thefield comprises information of the particular information type; if afield identified using the predetermined identifier is found in thefirst served information grouping, and the field contains the searchingtarget, then associating contents of the first served informationgrouping with the search results; and repeating the searching andassociating steps with other served information groupings using the samepredetermined identifier.

In accordance with a second aspect of the present invention, there isdisclosed a method for serving data in a distributed Internet network.The method generally comprises the steps of: receiving a request forinformation; and serving information of a particular information type,the information being served in a field identified using a predeterminedidentifier that identifies the field as containing information of theparticular information type.

These aspects of the invention and further advantages thereof willbecome apparent to those skilled in the art as the present invention isdescribed with particular reference to the accompanying drawings.

DESCRIPTION OF THE INVENTION

Embodiments of the invention will be described with reference to theaccompanying drawing figures wherein like numbers represent likeelements throughout. Before embodiments of the invention are explainedin detail, it is to be understood that the invention is not limited inits application to the details of the examples set forth in thefollowing description or illustrated in the figures. The invention iscapable of other embodiments and of being practiced or carried out in avariety of applications and in various ways. Also, it is to beunderstood that the phraseology and terminology used herein is for thepurpose of description and should not be regarded as limiting. The useof “including,” “comprising,” or “having” and variations thereof hereinis meant to encompass the items listed thereafter and equivalentsthereof as well as additional items.

The present invention provides methods for improving distributedInternet network searches. FIG. 1 is a block diagram embodiment of anexemplary file format or data structure 100 in accordance with an aspectof the present invention. The exemplary data structure 100 is a Web pagethat is computer readable but may also be human readable like a typicalWeb page. In the exemplary embodiment, the data structure relates to aparticular business or organization. One skilled in the art willrecognize that the structure may alternatively relate to any topic thatmight be a target of a network search.

A portion 110 of the data structure 100 contains information types thatremain relatively fixed. Examples of information types that may bestored in the fixed portion 110 include business name, businesscategory, business subcategory (one or multiple categories), physicaladdress/city/zip code, mailing address/city/zip code, global positioningsystem coordinates, operating hours, credit cards accepted, phonenumber, fax number, Web site, preferred contact method,products/services provide, specialty, brands, payment options, languagesspoken, certification & affiliation, to name a few.

Each information type within the fixed portion 110 is identified withinthe file format by a predetermined identifier. The predeterminedidentifier is standardized to facilitate searching. The fixed portion110 and predetermined identifiers 112, 114 and 116 may or may not bevisible on the Web page by human viewers.

The predetermined identifiers indicate that a portion or field withinthe fixed portion 110 contains information of a particular informationtype. The predetermined identifiers may be in the form of markuplanguage tags, key words, a database address and field location. Theymay utilize hyper text markup language (HTML) or extensible markuplanguage (XML). Identifier 112, 114 and 116 are examples ofpredetermined identifiers specifying where particular information typesare located. In this example, Zip code, GPS coordinates and credit cardsaccepted can be found in locations identified by identifiers 112, 114and 116 respectively.

The portions 120 and 130 of the data structure 100 are dynamic in naturein that they may change with some frequency. The information containedin those locations may change as it relates to the ongoing activities ofthe business or organization. Predetermined identifiers are also used inthose areas to improve searching. Portion 120 of the data structure 100contains optional dynamic business-provided data. For example, abusiness may place data in portion 120 relating to specials, discounts,reservations or appointments, waiting times, tickets and the like asmakes sense for the business or organization.

Portion 130 of the data structure 100 contains dynamic user-provideddata. Predetermined identifiers are also used in those areas to improvesearching. For example, a user may choose to place feedback or tags inportion 130, relating to his experience with the business ororganization (satisfied, un-satisfied, etc.), review(s), accuracy andrelevance of information provided, etc.

A search agent may be utilized to process and compile search data andpresent it to a device of the user's choosing. The search agent may becomprised of hardware and/or software, including machine readable codewhich when executed by a processor and/or memory, implements theintended functionality. The search agent may be a stand-alone program orapplication, or be part of a service the user pays for on an as-usedbasis or as part of an ongoing subscription. The search agent may beWeb-browser based. Alternatively, the agent may be embedded in aportable device that accesses the network through various channels(wired or wireless networks, etc.).

The data structure 100 in accordance with the present inventionfacilitates efficient, relevant and accurate Web searches by utilizingthe predetermined identifiers. For example, a user is at Fisherman'sWharf in San Francisco, Calif., and is interested in locating a seafoodrestaurant within walking distance (say half a mile), that accepts aparticular credit card, is moderately priced, has an informal dress codeand is open until 1:00 AM. Using conventional Web searching techniques,it is likely that multiple searches would be required on national,regional or local Web sites and even on individual restaurant Web sites.Even after all this searching, answers to the individual requirementsposed by the user may remain unanswered. Trying to make an informedcomparison and dining decision with limited information and possiblyerroneous information will likely be difficult, time consuming andunreliable.

Ambiguity problems inherent in current Web searching methods aretherefore eliminated by the use of predetermined identifiers. Faster andmore accurate searching can be facilitated as timely updates to a datastructure 100 are made, providing the most up-to-date informationinstead of searching archived or cached data and possibly performingcomplex natural language processing, tag searching or searching,processing and compiling of Web pages directly. The present inventioncan provide near-real time information which is not available withcurrent Web searching methods.

The present invention permits businesses or organizations that havetemporal data to enable users to access the data to help them makeinformed and timely decisions. For example, an airline or movie theatercould provide timely updates to changing seat availability up todeparture/show time, on a real-time or near-real-time basis. Thatinformation is marked by the standardized predetermined identifiers ofthe invention, and information from several airlines can therefore beconveniently compared. Similarly, restaurants may make wait timesavailable to keep users informed as they make dining decisions. A mobilefood service cart or truck service providing meals or snacks couldprovide updates as to its location as this can change from day-to-day oreven hour-to-hour. A restaurant could also provide updates as to a dailyspecial or soup of the day, as they may also change with some frequency.The predetermined identifiers of the present invention permit thatinformation to be found and compared in near-real-time, without relyingon Web crawlers to compile the data.

In another embodiment, a search agent and delivery service may encryptpart or all of the data structure, thereby limiting access. For example,access to sensitive financial information, such as a bank account orinvestment portfolio, or personal information, such as physical address,email address or personal phone number, may be restricted. Access maythen be granted only with appropriate permission and security asestablished by the service providing the information.

In one example, a restaurant or nightclub may wish to promote anupcoming event with special privileges reserved for VIP club members. Byencrypting business-provided data in the data structure, access to theVIP information may be limited to registered VIP members who then use aprovided decryption key, for example, via a VIP email or SMS message.Similarly, information services, such as a subscription-only database,an employment service or a dating service, may utilize encryption ofportions of the data structure to grant various levels of access toinformation. The access may depend on the subscription level selectedand/or other safety measures put in place to safeguard entrustedintellectual property, proprietary information, client informationand/or personal information.

In yet another embodiment, a notification of a change to a datastructure 100 is sent by the business or organization owning ormaintaining the data structure to a search engine or search agent,alerting them of changes in a timely way. Where data is updatedfrequently, such as daily, hourly, or by the minute, that techniqueassures that the most current information is returned in a search.

FIG. 2 is a flow chart depicting a method 200 for searching for data inaccordance with the present invention. In step 210, a searching targetis received, the target comprising a particular information type. Theparticular information type is chosen from a predetermined list ofinformation types that are each associated with one or morepredetermined identifiers. Examples of information type may includebusiness name, business category, business subcategory (one or morecategories), physical address/city/zip code, mailing address/city/zipcode, global positioning system coordinates and others.

In step 220, a search is made. A first served information grouping issearched for a field identified using a predetermined identifierindicating that the field comprises information of the particularinformation type. An example of that search could be searching the Zipcode field for a particular Zip code, such as 94133 for Fisherman'sWharf, San Francisco, Calif. The predetermined identifier unambiguouslyidentifies information in the indicated field as being the particularinformation type. No natural language interpretation is necessary.

In step 230, if a field identified using the predetermined identifier isfound in the first served information grouping, and that field containsthe searching target, then an association is made between the contentsof the field and the search results. Using the Zip code 94133 example,when a field identified by a predetermined identifier for Zip codes isfound, and that field contains 94133, an association is made between theWeb site containing the field and the search results. For example, Websites containing 94133, identified as a Zip code, are added to a resultlist. On the other hand, if a Web site contains “94133” in anothercontext, such as a street number or a phone number, that Web site wouldnot be added to the search results on that basis.

In step 240, the searching and associating steps are repeated in otherserved information groupings using the same predetermined identifier. Anexample of this step would include continuing to search and associateusing zip code 94133 and associating as appropriate.

FIG. 3 is a flow chart depicting a method 300 for serving data inaccordance with the present invention. In step 310, a request forinformation is received. An example of this is a search request forrestaurants which serve seafood located in the Zip code of 94133(Fisherman's Wharf, San Francisco, Calif.). In that case, thepredetermined identifier is “Zip code.”

In step 320, information of a particular information type is served in afield identified using a predetermined identifier that identifies thefield as containing information of the particular information type: i.e.“Zip codes.” The served information therefore unambiguously contains aZip code. A search engine or agent can use the information directly,without interpretation or parsing.
